Charles Sheldon was a 19th century American Congregational minister. He became a part of the Christian Socialism movement in the last part of the 19th century. He gave less importance to the doctrinal traditions and more emphasis on the practicalities of moral life. In His Steps: "What Would Jesus Do" was published in 1896. It is listed as the 39th most popular best selling book ever written. Because of an improper copywrite, the book was published in several forms and at a reduced price, which helped increase it's sales.
